Question

Answer the following.

Answer 1

Explanation:

1)
`y=2sin(x)/(2) -2`

Altitude = 2

Period = 2pi/(1/2) = 4pi

(since 1/2 is coefficient of x)

Altitude interval = [-4,0]

Domain interval = set of all real numbers

Phase shift = 0

Vertical shift = 2 down

2) y=-4sin(2x+pi/2)-2

Altitude = 4

Period = 2pi/(2) = pi

(since 2 is coefficient of x)

Altitude interval = [-6,2]

Domain interval = set of all real numbers

Phase shift = pi/2

Vertical shift = 2 down
